TLDR
Two non-inhibitory media tryptone glucose agar and Trypticase soy agar showed more neutralizing capacity than eosin methylene blue agar, and the neutralizing effect appeared to be a function of the soluble component of the media and not of the agar itself.Abstract:
Increasing use of silver in the treatment of water has necessitated an examination of microbiological methods for the measurement of silver inactivation of microorganisms. Three common agar media were tested for their ability to neutralize the bacteriostatic effects of silver. Results suggested that growth media differed in their neutralizing capacity; that is, the non-inhibitory media tryptone glucose agar and Trypticase soy agar showed more neutralizing capacity than eosin methylene blue agar. Furthermore, the neutralizing effect appeared to be a function of the soluble component of the media and not of the agar itself.read more

Antimicrobial activity and action of silver
A. D. Russell,W B Hugo +1 more
TL;DR: This chapter discusses antimicrobial activity and action of silver, one of the native metals and second only to gold in its stability amongst the metals of antiquity, and its salts and complexes with proteins and other macromolecules.

Silver-ion-mediated reactive oxygen species generation affecting bactericidal activity.
TL;DR: It is found that silver-ion-mediated ROS-generation affected bactericidal activity and silver ions strongly enhanced paraquat-induced oxidative stress, indicating close correlation and synergism between the conventional and ROS-mediated silver toxicity.
The Molecular Mechanisms of Copper and Silver Ion Disinfection of Bacteria and Viruses
TL;DR: In this article, the effect of metal ion-biomolecule interaction on cell or capsid protein surface or on the nucleic acid of cells or viruses is discussed. But the authors do not consider the effects of metal ions on viruses.

TL;DR: Comparison of the antibacterial as well as the biocompatible potential of different metal ions in vitro reveals an outstanding position of copper ions as antibacterial but nevertheless bio-tolerant additive.

Interaction of amino acids with silver(I) ions.
TL;DR: The reactivity of silver(I) ions towards twenty amino acids has been studied in aqueous unbuffered solutions using an ion-selective electrode as a highly sensitive monitor, finding the interaction with all of these species except cysteine is too weak to affect significantly the determination of thiol in proteins by the customary argentometric titration method.

Bactericidal Effect of Low Concentrations of Silver
TL;DR: The effect of oligodynamic silver on organisms was first described in 1869 and since then it has frequently been reported that silver added to water as a colloidal suspension, by filter beds or electrolytic devices, has greater bactericidal efficiency than an equivalent amount of silver added as silver nitrate as discussed by the authors.

Silver Sulfadiazine: Effect on the Growth and Metabolism of Bacteria
TL;DR: In this paper, the addition of silver sulfadiazine (AgSu) to purified deoxyribonucleic acid (DNA) results in the formation of AgSu-DNA complexes, no such complexes were detected in bacteria treated with AgSu.
Silver Sulfadiazine: Effect on theGrowthand Metabolism ofBacteria
TL;DR: Radioactive AgSu was localized mainly in the cytoplasmic membrane fraction of treated cells and blocked macromolecular syntheses in treated bacteria, DNA synthesis being slightly more sensitive to this inhibitory action.
